Description

Technical Field

[0001] This utility model relates to a tooling, and more particularly to a contour positioning tooling. Background Technology

[0002] During the processing and assembly of the product, there are assembly or processing steps on multiple sides of the product shell. It is necessary to position one side of the product shell according to the processing or assembly steps. After positioning, routine operations such as screwing on the shell, installing accessories on the shell, or wiring on the shell are performed.

[0003] In the market, product vertical positioning is generally achieved using tooling templates. For example, patent CN211439061U discloses an integrated fixture for the front and back sides of a mechanical grinding wheel, including a base. Two opposite sides of the base are respectively provided with a front clamping groove for accommodating the front side of the workpiece and a back clamping groove for accommodating the back side of the workpiece. The base also has fixing components for clamping and securing the workpiece. Changing this tooling template structure from front-side positioning to back-side positioning requires flipping the template to turn the lower back clamping groove upwards, adding a step and reducing work efficiency. Furthermore, the tooling template has a certain weight, and manual flipping increases the labor intensity for workers.

[0004] To solve the above problems, some designs place the front and back positioning grooves on the same side of the tooling template. For example, patent CN217317657U discloses a fixture that can realize front and back processing, which includes an upper fixed plate and a lower fixed plate. The upper fixed plate has a left product area and a right product area in the middle. The left product area and the right product area are used to place the front and back sides of the positioning product, respectively.

[0005] The aforementioned problems arise from setting the front and back positioning grooves on the same surface of the tooling template. The front and back positioning grooves are located in different areas of the tooling template surface—one on the left side and the other on the right side—with a certain distance between them. This structural arrangement requires a larger tooling template, increasing material costs. Furthermore, this size tooling template occupies a larger workbench area, thus increasing the production line length, production line costs, and space costs. Switching the product's positioning surface requires moving the product from one side to the other, a process that involves workers carrying the product a considerable distance, reducing production efficiency. Utility Model Content

[0006] Based on the fact that the positive and negative positioning grooves are independently set on two different areas on the surface of the tooling template, a larger tooling template is required to set the positive and negative positioning grooves, which increases the material cost accordingly. Moreover, the tooling template of this size needs to occupy a large area of ​​the workbench, thereby increasing the length of the production line, increasing the production line cost and space cost. When switching the product positioning surface, the product needs to be moved from one side to the other side. This process involves a certain distance for workers to carry the product, which reduces the production efficiency. This utility model provides a contour positioning tooling.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a contour positioning fixture, including a fixture template for positioning a placed workpiece, wherein the fixture template is provided with a positioning groove corresponding to a reference part on the first surface of the workpiece and a receiving groove corresponding to other parts on the first surface of the workpiece, wherein the positioning groove is configured to be contoured to the shape of the corresponding reference part, and at least one receiving groove on the fixture template is provided with a part that is contoured to the reference part on another surface of the workpiece, wherein the contoured part in the receiving groove is used to cooperate with the reference part on another surface of the workpiece that enters the receiving groove, so as to position the workpiece on the fixture template.

[0008] A further preferred technical solution of this utility model is as follows: the tooling template is used to position the front and back sides of the workpiece. The tooling template is provided with a positioning groove corresponding to the reference part on the front side of the workpiece and a receiving groove corresponding to other parts on the front side of the workpiece. At least one receiving groove on the tooling template is provided with a part that is similar in shape to the reference part on the back side of the workpiece.

[0009] A further preferred technical solution of this utility model is as follows: the workpiece is a machine tool head, which includes a housing and two annular handles. A raised ring is provided in the middle of the housing, dividing the housing into an upper part and a lower part. The two handles are respectively provided on both sides of the raised ring. The tooling template is provided with a positioning groove corresponding to the handle part on the front of the machine tool head, as well as a receiving groove corresponding to the raised ring and the upper part on the front of the machine tool head. The positioning groove is set to be similar in shape to the handle part on the front. The receiving groove includes an upper groove for receiving the raised ring and a lower groove for receiving the upper part. A step is formed between the upper groove and the lower groove to support the raised ring. The lower groove is provided with a part similar in shape to the reference part on the lower part. When the machine tool head is reversed and mounted on the tooling template, the lower part is inserted into the lower groove and the raised ring abuts against the step. The reference part on the lower part and the corresponding similar part on the lower groove cooperate to vertically position the machine tool head.

[0010] A further preferred embodiment of this utility model is that the receiving groove is a through groove.

[0011] A further preferred embodiment of this utility model is as follows: the inner wall surface of the front side of the lower groove is configured to resemble the shape of the front side of the lower part of the machine tool head, forming a first similar shape; the two ends of the inner wall surface of the rear side of the lower groove are configured to resemble the shape of the two ends of the rear side of the lower part of the machine tool head, forming a second similar shape; the width between the first and second similar shapes is the same as the width between the corresponding positions on the front and rear sides of the lower part; the portions of the inner wall surfaces on the left and right sides of the lower groove that are adjacent to the inner wall surface of the front side resemble the shape of the left and right sides of the lower part of the machine tool head, forming a third similar shape; the width between the third similar shapes on both sides is the same as the width between the corresponding positions on the left and right sides of the lower part.

[0012] A further preferred embodiment of this utility model is that the tooling template is provided with mounting holes, which are located at the edge of the tooling template.

[0013] A further preferred technical solution of this utility model is: the tooling template is provided with a groove located around the positioning groove or receiving groove, and the groove is connected to the positioning groove or receiving groove.

[0014] Compared with the prior art, the advantages of this utility model are that by setting positioning grooves corresponding to the reference parts on the first surface of the workpiece and receiving grooves corresponding to other parts on the first surface of the workpiece on the tooling template, and setting parts on the receiving grooves that are similar in shape to the reference parts on other surfaces of the workpiece, a single tooling template can be used to position at least two surfaces of the workpiece. Since parts that are similar in shape to the reference parts on other surfaces of the workpiece are set in the receiving grooves corresponding to other parts on the first surface, when assembling and positioning these two surfaces of the workpiece by the tooling template, the assembly and positioning areas of these two surfaces of the workpiece at least partially overlap. Compared with the tooling structure in which two positioning grooves are independently set in two positions, this tooling structure has a higher integration of single operation processes, reduces the number and size of working templates, reduces tooling costs, shortens the length of the production line, reduces production line costs and space costs, reduces personnel running distance, and improves production efficiency.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0027] Figures 1-8 As shown, the contour positioning fixture includes a fixture template 1 for positioning the placed workpiece. Assembly operations are performed by positioning the workpiece on the fixture template 1, such as installing accessories, screwing, wiring, and other routine operations on the workpiece.

[0028] Figures 1-5As shown, the tooling template 1 is provided with a positioning groove 2 corresponding to the reference part on the first surface of the workpiece and a receiving groove 5 corresponding to other parts on the first surface of the workpiece. The positioning groove 2 is set to be similar in shape to the corresponding reference part. When positioning the first surface of the workpiece, the reference part on the first surface of the workpiece is inserted into the positioning groove 2 and cooperates with the similarly shaped positioning groove 2. The reference part serves as an effective fulcrum for the first surface of the workpiece, enabling the workpiece to be vertically positioned on the tooling template 1. In this vertical positioning state, other parts on the first surface of the workpiece are received in the corresponding receiving groove 5. The receiving groove 5 avoids the other parts on the first surface of the workpiece from interfering with the tooling template 1 and affecting the complete fit between the reference part on the first surface of the workpiece and the similarly shaped positioning groove 2.

[0029] Figures 6-8 As shown, at least one receiving groove 5 on the tooling template 1 is provided with a part 6 that is similar in shape to the reference part on other surfaces of the workpiece. When positioning other surfaces of the workpiece, the workpiece is flipped so that the surface of the workpiece to be positioned is facing downwards and opposite to the tooling template 1. The reference part on this surface is inserted into the receiving groove 5 and cooperates with the similar part 6 provided in the receiving groove 5. The reference part serves as an effective fulcrum for the surface of the workpiece to be positioned, so that the workpiece can be vertically positioned on the tooling template 1.

[0030] Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, according to the process route and assembly flow of the processed object, one side of the processed object is first vertically positioned by the tooling template 1. After the operation is completed, the processed object is flipped so that the other side of the processed object that needs to be positioned faces down towards the tooling template 1. The processed object is then assembled and positioned on the tooling template 1, and the worker performs the assembly operation on the processed object.

[0031] This patented structure enables a single tooling template 1 to position at least two surfaces of a workpiece requiring positioning. Because the receiving grooves 5 on other parts of the corresponding first surface have portions 6 that resemble the reference portions on other surfaces of the workpiece, when these two surfaces are assembled and positioned using the tooling template 1, the assembly and positioning areas of these two surfaces at least partially overlap. Compared to a tooling structure where two positioning grooves 2 are independently located in two positions, this tooling structure achieves higher integration of single-operation processes, reduces the number and size of working templates, lowers tooling costs, shortens the production line length, reduces production line and space costs, reduces personnel running distance, and improves production efficiency. This positioning structure can also be applied to tooling designs requiring positioning of multiple surfaces.

[0032] Preferably, the tooling template 1 is used for vertical positioning of the front and back sides of the workpiece. The tooling template 1 is provided with a positioning groove 2 corresponding to the reference part on the front side of the workpiece and a receiving groove 5 corresponding to other parts on the front side of the workpiece. At least one receiving groove 5 on the tooling template 1 is provided with a part 6 that is similar in shape to the reference part on the back side of the workpiece.

[0033] Specifically, the object being processed is a tool head 7, such as the tool head 7 of a handheld electric mixer. The tool head 7 includes a housing and two annular handles 9. A raised ring 10 protrudes from the center of the housing, dividing the housing into an upper part 11 and a lower part 8. The two handles 9 are respectively located on both sides of the raised ring 10, and the housing and the handles 9 on both sides are divided into an upper half and a lower half from the middle. The upper half and the lower half are joined together and fixed together with screws. On the front of the tool head 7, the handles 9 on both sides are defined as the reference points for effective fulcrum positioning. The upper part 11 and the raised ring 10 on the front are defined as other parts. On the reverse side of the head 7, at least one part on the lower part 8 is designated as a reference part as an effective fulcrum for reverse positioning. The tooling template 1 is provided with a positioning groove 2 corresponding to the handle 9 part on the front side of the head 7 and a receiving groove 5 corresponding to the protruding ring 10 and the upper part 11 on the front side of the head 7. The positioning groove 2 is set to be similar in shape to the handle 9 part on the front side. The receiving groove 5 includes an upper groove 12 for receiving the protruding ring 10 and a lower groove 13 for receiving the upper part 11. A step is formed between the upper groove 12 and the lower groove 13 to support the protruding ring 10. The lower groove 13 is provided with a part 6 similar in shape to the reference part on the lower part 8.

[0034] When the machine tool head 7 is positioned on its front side by the tooling template 1, the machine tool head 7 is placed on the tooling template 1, and the handles 9 on both sides of the front side of the machine tool head 7 are positioned in the positioning groove 2 to prevent the machine tool head 7 from moving horizontally. The protruding ring 10 and the upper part 11 on the front side of the machine tool head 7 are inserted into the receiving groove 5. At this time, the tooling template 1 forms a vertical positioning for the front side of the machine tool head 7. When it is necessary to vertically position the back side of the machine tool head 7, the machine tool head 7 is turned over and mounted on the tooling template 1. The lower part 8 of the machine tool head 7 is inserted into the lower groove 13. The reference part on the lower part 8 and the corresponding similar part 6 on the lower groove 13 cooperate, so that the machine tool head 7 cannot move horizontally relative to the tooling template 1. The protruding ring 10 on the back side abuts against the step to support the machine tool head 7. At this time, the tooling template 1 forms a vertical positioning for the back side of the machine tool head 7.

[0035] The inner wall surface of the front side of the lower groove 13 is configured to resemble the shape of the front side of the lower part 8 of the tool head 7, forming a first similar shape part 6. The two ends of the inner wall surface of the rear side of the lower groove 13 are configured to resemble the shape of the two ends of the rear side of the lower part 8 of the tool head 7, forming a second similar shape part 6. The width between the first similar shape part 6 and the second similar shape part 6 is the same as the width between the corresponding positions on the front and rear sides of the lower part 8. The parts of the inner wall surfaces on the left and right sides of the lower groove 13 that are adjacent to the inner wall surface on the front side resemble the shape of the left and right sides of the lower part 8 of the tool head 7, forming a third similar shape part 6. The width between the third similar shape parts 6 on both sides is the same as the width between the corresponding positions on the left and right sides of the lower part 8. This structure allows the lower part 8 of the tool head 7 to cooperate with the similar shape parts 6 on the inner wall surface of the lower groove 13 when it enters the lower groove 13, thus positioning the four sides of the tool head 7 and restricting the horizontal movement of the tool head 7 and the tooling template 1.

[0036] Figure 1 As shown, preferably, the receiving groove 5 is a through groove. When the upper part 11 or the lower part 8 is longer than the thickness of the tooling template 1, the through receiving groove 5 will not interfere with the inserted upper part 11 and lower part 8, which facilitates the assembly and positioning of the tool head 7.

[0037] The tooling template 1 is provided with mounting holes 4, which are located at the edge of the tooling template 1. The tooling template 1 can be fixedly installed through the mounting holes 4, for example, by mounting the tooling template 1 on a tooling table or on a bracket.

[0038] Figure 4 As shown, the tooling template 1 is provided with a groove 3 located around the positioning groove 2 or the receiving groove 5. The groove 3 is connected to the positioning groove 2 or the receiving groove 5. The groove 3 facilitates the insertion of fingers to remove the processed object that is assembled and positioned on the tooling template 1.

Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
